通过@Value注解读取.properties配置内容

@Controller @RequestMapping("/value") public class ValuePropertyController extends ApplicationController{ @Value("#{configProperties['jdbc.jdbcUrl']}") private String jdbcUrl; @RequestMapping public String value(){ System.out.println(jdbcUrl); return ""; } }

applicationContext.xml

<bean id="configProperties" class="org.springframework.beans.factory.config.PropertiesFactoryBean"> <property name="locations"> <list> <value>classpath:database.properties</value> </list> </property> </bean> <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PreferencesPlaceholderConfigurer"> <property name="properties" ref="configProperties" /> </bean>

database.properties

jdbc.jdbcUrl=jdbc:mysql://localhost:3306/commentDemo?useUnicode=true&characterEncoding=UTF-8
